Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed July 19, 1906. Serial No- 326,897.

To all whom it may concern:

Be it known that I, HARRY W. BOLTZ, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Combination- Tools;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has reference to compound tools, and especially to thatclass of tools which combine in a single structure means for setting,driving, and extracting nails, tacks, brads, pins, and the like, theobject of the invention being to provide a simple, convenient, andefficient tool of the above class, which is cheaply formed, easilyassembled, and is durable.

To this end, the invention resides in a tool having a hollow handle anda head or body upon which are formed an extracting claw and a hammer,and a supplemental handle movable longitudinally within the hollowhandle, the opposite end of the supplemental handle being provided withfixed and movable extracting jaws.

A further improvement consists in forming a longitudinal groove in thesupplemental handle, and in providing a spring shoulder within thehollow handle for engagement in said groove, whereby the position of thehollow .and supplemental handles may be adjusted with respect a eachother, making it possible to in-. crease the leverage of either toolhead at will.

Further improvements consist in the provision upon the movable jawattached to the supplemental handle, of a bearing-arm having transverseextensions at its free end, thus affording a greater bearing surface andpermitting the nails &c. to be drawn with greater facility.

The invention further consists in the particular construction,combination, and arrangement of the several elements which form thetool, as hereinafter fully described, specifically claimed andillustrated in the accompanying drawings, in which- Figure l is a frontelevation of the tool. Fig. 2 is a transverse section taken on the line2-2 of Fig. 1.

Fig. 3 is a longitudinal vertical section taken approximately on theline 3-3 of Fig. 2. Fig. 4 is a detail view of the fixed member of thenail-puller. Fig. 5 is a similar view of the movable member thereof.

Like parts are designated by corresponding reference numerals in theseveral views.

Referring more particularly to the drawings, the tool is shown asconsisting of a tack-puller 10, the head of which is formed at oppositeends with the extractingclaws 11, and hammer 12, of any preferreddescription. The handle of the tack-puller is hollow, as indicated bynumeral 13, and is provided on opposite sides with of the hollow handleof the tack-puller at the lower end thereof is a spring dog 19, normallyin engagement in the groove in said supplemental handle. It is thuspossible to increase the leverage of both the tack-puller and thenail-puller by merely drawing out the supplemental handle the requireddistance, the dog 19 retaining said parts in such adjusted position. Towithdraw the nail-puller and its handle entirely from the hollow handleof the tack-puller it is only necessary to slide the former outwardlyuntil the dog 19 is in line with the transverse extension 18 of groove17; the tack-puller is then turned to the right until the end of thegroove extension is reached, when the dog will be pressed back betweenthe curved face of the supplemental handle and that of the main orhollow handle, and the former then readily withdrawn, the grooveextension being of gradually decreased depth to permit such action.

The nail-puller 16, as shown, comprises a fixed jaw or member 20 securedin any way to the supplemental handle 15 or formed integral therewith,if desired, and a movable member 21 fastened to the fixed member by apivot bolt 22.

The movable member 21 is provided with a transverse jaw 23 and beak 24cooperating respectively with a similar jaw 25 and beak 26, formed onthe fixed member 20. The movable member is further provided with acurved arm 27, oppositely disposed with respect to the stem of jaw 23,the free end of said arm being provided at opposite sides withtransverse extensions 28 forming an enlarged or extended fulcrum.

The jaws 23 and 25 and beaks 24 and 26 of the movable and fixed membersrespectively are normally held apart through the medium of a coiledspring 30 secured in corresponding curved recesses 29 formed in theinner face of said members.

The sides of the main handle may be calibrated as at 31, if desired.

The operation of the device will be apparent from the foregoing, andfurther description thereof is thought unnecessary beyond the statementthat the extractingclaw 11 of the tack-puller is used in connection withtacks or small pins while the beaks 24 and 26 and jaws 23 and 25 of thenail-puller are used for withdrawing spikes, large nails, or brads.

Owing to the sliding adjustment of the supplemental handle within themain handle, the leverage of either tool may be increased at will andfurthering the effi-' ciency of both, the coaction between the dog andgroove retaining the parts in position when adjusted. The provision ofthe transverse extensions 28 upon the arm 27 of the movable member ofthe nail-puller affords an increased bearing surface, the advantage ofwhich is obvious.

It is further to be noted that the entire device consists of but fourparts, VlZ., the main or hollow handle with its hammer and claw, thesupplemental handle and fixed member, the movable member, and the springdog. The cheapness with which the entire device may be manufactured istherefore apparent, and its several parts may be readily and quickly puttogether. It will be equally obvious from the foregoing that thesupplemental handle may be entirely withdrawn from the main or hollowhandle, thus forming two separate tools.

Slight changes may be made in the size and location of the several partsand in the minor details of construction of the same without departingfrom the spirit of the invention, which is therefore not intended to belimited to the exact details shown and described.

What is claimed, is

A tool comprising a main handle provided with a longitudinal bore havinga seat formed therein at its outer end; a supplemental handle slidablewithin said bore and provided with a longitudinal groove having atransverse extension of gradually decreased depth at its inner end; anda resilient member secured at one end within the seat in said here andhaving its free end extending rearwardly into the groove in saidsupplemental handle.

In testimony whereof, I afiix my signature, in presence of twowitnesses.

HARRY W. BOLTZ.
